lTILE Foa WELLS AND CISTERNS.

SPECIFICATION forming part of Letters VIIEatent No. 265,277, dated October 3, 1882.

Application filed May 517, 1882. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. OVERALL, of Memphis, in the county of Shelby and State of Tennessee, have invented certain new and useful Improvements in Tiles for Wells and Cisterns; and 1 dohereby declare that the following is afull, clear, and exact description ot' the invention, which will enable others skilled in the art to which it appert-ains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification. Figure l is a vertical sectional view of my improved cistern, and Fig. 2 is a detail view, in persptctive, of one ofthe intermediate sections composing the same.

Corresponding parts in the several igures are denoted by like letters ot' reference.

This invention relates to cisterns or waterreservoir-s; and it consists in certain improvements in the construction ot' the same, which will be hereinafter fully described, and particularly pointed out in the claims.

My improved cistern is constructed of a bottom section, A, a top section, B, and one or more intermediate sections, C, all molded or formed in any suitable manner ot' clay, cement, artificial stone, or ot' any other material suitable for the purpose intended. The lowermost or bottom section, A, which may be ot' any vsuitable size, is bowl-shaped, as shown, and

its upper edge is provided with an annular groove, D. The intermediate section or sections, O, are tubular in shape and tapering, as shown, each section being' smaller than the one below, so as to form a gradual incline in an upward direction. Each section C is pro- Avided at its lower edge with an annular tlange it is provided with a stren gthenin g or re-enforcing rim, H, forming the mouth of the cistern.

1n operation, a suitable excavation is made, and the bowl or bottom section, A, carefully set therein. Mortar or cement is now placed in the groove D, and the first intermediate section, C, is then lowered and set with its flange E in the cement in groove D, which soon hardens and forms a water-tight joint. Other sec tions O may now in like manner be added, and finally the top section, B,which completes the curbing' ot' the cistern, around which the earth may then be packed.

By my invention a cistern may be easily constructed of any desired capacity by using any desired number of the intermediate sections, C, before the top section, which is tted to the uppermost intermediate section,is'put in place. The sections may be made of burnt clay or tiling, which is absolutely water-proof, and the joints herein described make the cistern absolutely tight, so as to prevent it from absorbing impurities from 'the earth in which it is Set.

Having' thus described my invention, l claim and desire to secure by Letters Patent of the United Statesl. A cistern consisting ot' a bowl-shaped bottom section, tubular tapering intermediate sections, and a top section, all constructed and arranged substantially as set forth.

2. The herein-described cisternfcurbing, consisting ot' the bowl-shaped bottom section, A, having groove D, one or more tubular tapering intermediate sections, G, each having a tongue or tlange, E, and groove F, and the top section, B, having tongue Gr and rim H, as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
